| Abstract: | To overcome the defect that the traditional optical correlator can not recognize nearly identical images,an phric hybrid system is proposed and constructed.The experimental results show that this system has a strong capability for recognition of images with small difference, besides the system is very simple and processing is quasi-realtime. |
